Where You’ve Seen Her: Alyson Hannigan has been known for sticking things up her you-know-what (vagina), but that certainly hasn’t stopped her from breaking the mold of her image. She played a nerd, and later a lesbian on Buffy The Vampire Slayer, which was a great show if you like overdramatic soap operas but hate the high lighting and lack of ridiculous plots that take 3 or 4 seasons to even begin making any sense. Alyson is now a regular on the hit show How I Met Your Mother.

MILF Status: Hannigan has a daughter named Satyana, born in March of this year, with actor Alexis Denisof.
